Foreword

The African Organization for Standardization (ARS) is an African intergovernmental organization
made up of the United Nations Economic Commission for Africa (UNECA) and the Organization of
African Unity (AU). One of the fundamental mandates of ARSO is to develop and harmonize African
Standards (ARS) for the purpose of enhancing Africa’s internal trading capacity, increase Africa’s
product and service competitiveness globally and uplift the welfare of African communities. The work
of preparing African Standards is normally carried out through ARSO technical committees. Each
Member State interested in a subject for which a technical committee has been established has the
right to be represented on that committee. International organizations, regional economic
communities (RECs), governmental and non-governmental organizations, in liaison with ARSO, also
take part in the work.

ARSO Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare ARSO Standards. Draft ARSO Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
ARSO Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ARSO shall not be held responsible for identifying any or all such patent rights.

Introduction

This revised standard has incorporated the specific compositional requirements for wheat flour. The
standard has prescribed the permissible levels of food additives in wheat flour. Microbiological
requirements for wheat flour have also been stipulated.

This African Standard is a technical revision of the earlier ARS 470:1987(E), Wheat flour —
Specification which is hereby superseded and cancelled.

1 Scope
